Spiral Bevel gears

A mental exercise involved crafting spiral bevel gears without using specialized software. I tried employing a circular path for the spiral trajectory via Gleason system, but was unsuccessful. I'm still puzzled by how the Gleason system works and couldn't get correctly meshing pair of spiral bevel gears. Thus, I found that helical spirals were the only way to effectively model these gears. These gears lack a shifted teeth profile and their clearance between teeth isn't constant like other gear types.
